Product Classification

To reduce coronary artery stenosis by dilatation of the balloon and by apposition of the cutting/scoring surfaces to the stenotic material for the treatment of coronary artery stenosis to improve myocardial perfusion.

Physical State

Cutting/scoring PTCA catheters are usually comprised of flexible polymers for the catheter body and a compliant polymer for the balloon. The cutting/scoring elements are usually metal.

Technical Method

The device functions independently, but is typically placed using a guidewire and guiding catheter. The balloon is inflated by the infusion of liquid through the body of the catheter. Following treatment, the liquid is withdrawn, the balloon is deflated and then withdrawn from the body.
